This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether exercise during pregnancy—specifically aerobic exercise (like treadmill or cycling), resistance training (like weights), or a combination of both—can help protect your child from developing obesity later in life. Researchers want to find out which type of exercise works best for both you and your baby during pregnancy.
Childhood obesity is a serious health problem in the United States, and research shows that a child's weight can be influenced even before birth. This treatment gap exists because doctors don't yet know which specific exercise approach during pregnancy is most effective at helping prevent obesity in children.

If you join, you would be assigned to one of three exercise groups: aerobic exercise (using machines like treadmills or stationary bikes), resistance training (using weights), or a combination of both. You would exercise about 150 minutes per week at moderate intensity throughout your pregnancy. The study team will monitor your health and your baby's development, and they will follow up with your child after birth to track their growth and health outcomes over time.
